Wed, 20 Sep 2017 00:43:27 +0000http://johnr.hifizine.com/?p=767#comment-67259My EW M30 and iMM6 calibrated are a very good match up to above 10k, and this is feeding quite different RTAs, the dbx RTA1 and an iPhone5S running S6D AT. Nothing like any major delta 100-400Hz. In prior comparison M30 was v close match to B&K quarter- and half-inchers.
Not seeing how cal file is clearly off either, so I am missing something wrt ripple >4k.
Finally, 90deg cal might be nice (for grazing work?) but do not see why needed, really, for HT EQ regardless.

Sat, 06 May 2017 15:07:38 +0000http://johnr.hifizine.com/?p=767#comment-65627I have compared the Umk-1 with the mini DSP cal file, the Dayton Audio EMM-6 with the CSL cal file using an Art dual mic preamp, both on the Ipad pro, with an Ivie IE-10 A and a lowly Tenma 72-942 SPL meter.
All calibrated with a B&K 4230 calibrator at 93.8 dB.

My Octave band SPL results using Audio Tools were within 2-3 dB of all except for the Umk-1, which read considerably higher at ambient room tone measurements. I had hoped that the Umk-1 and my ipad would have been my inexpensive portable iOS rig. I regrettably am not comfortable with the Umk-1 doing any serious measurements.
I have a feeling that the Audio Tools iTest mic may be the best solution for class 2 portable acoustic testing on iOS devices at this time.
I’ll post again when I buy and test it.

Wed, 11 Jan 2017 19:05:03 +0000http://johnr.hifizine.com/?p=738#comment-64481Hi John,
Did you complete the 2,5 way version of the convertible? The reason why I ask is that I am going down the same path. I am just about completing a build with the following parts: Scanspeak D2905/9900 tweeter and 2 pcs Scanspeak 18W8545K woofers. The lower woofer with a passive lowpass filter at around 300 Hz and second order (coil and capacitor). Plate amp is the Minidsp PWR-ICE250. The cabinets are original Magico V2’s. Bought from an auction related to the broke cabinet builder Hornslet Kabinetfabrik in Denmark. I am looking very much forward to testing – also because Minidsp has updated the plateamp with FIR possibilty (limited however). The reason why I write is to learn from your overall experience and the combination of dsp and passive x-over.
MANY THANKS IN ADVANCE FOR YOUR KIND REPLY!!
Best regards from Denmark,
Jørgen Dybro

Can you directly use the minidsp’s usb input from volumio or RuneAudio? HifiBerry is not needed at all? Any problems with this setup?
Thanks!

Sat, 25 Jun 2016 03:29:44 +0000http://johnr.hifizine.com/?p=720#comment-62670Hi Julio, Dave Pellegrene seems to not be making them any more. You could try the Visaton WG148R or the diysoundgroup SEAS-8 as possible alternatives. (Don’t have either of them myself yet.)

Well, it’s mentioned now 😉 FWIW I use Soundflower on my Mac Mini running OSX 10.10 and haven’t had any problems. I don’t use it with REW, admittedly, but as now noted in the opening to this (old) tutorial, you most likely don’t need it since JohnM updated REW anyway.
